The main component of DEFINITY ProLogix Solutions is the new R7csi model, which uses the TN798B processor (a RISC-based central processing unit) and TN2182B Tone-Clock. The TN798B supervises system operation.

Cabinets

Cabinets are enclosed shelves composed of vertical slots that hold circuit packs. Circuit packs make up the logic, memory, and switching circuitry for the system. Port circuit packs connect to telephones, computers, and trunks. The cabinets are designed to accept any type of port circuit pack in each circuit pack position.

The circuit packs fit into connectors attached to the rear of the slots. Every connector is connected to signal buses and power supplies in the cabinet. The cabinets also house the equipment that supplies ringing signal voltage and mass storage for software translations. Each compact modular cabinet has its own power supply and supports 10 universal slots. The first cabinet uses two slots for the processor and the tone clock.
